YARN CLEANER.

Original application tiled February 14, 1923, Serial No. 618,383.

Serial No. 34,787.

This invention relates to yarn cleaners for eliminating from yarn impurities such as parts of seeds, parts of stems, slubs, specks, grains of sand and other particles before the yarn is made into cloth, and thus iinproving the quality of the cloth made from the yarn and avoiding the necessita7 for excessive bleaching of the cloth.

The invention aims to provide a simple i0 device adapted vthoroughly to clean a traveling yarn.

A cleaner provided with a number of blades which are mechanically reciprocated rapidly in directions substantially longitudinal of the yarn is described and claimed in my copending application filed February7 14, 1923, Serial No. 618,883` of which this application is a division. This parent application is now patent No. 1,541,448, June 9, 1925.

The invention to Which the present application is directed relates to mechanical means for reciprocating the blades herein described in detail with reference to the accompanying drawings in which- Fig. 1 is a top view of the cleaner in which the blades are reciprocated in curves tangential to the yarn;

Fig. 2 is a transverse section of the cleaner 2o shown in Fig. 1 on the line 2-2 of Fig. 1;

Fig. 3 is a rear end view of the cleaner shown in F ig. 1; and

Fig. 4 is a fragmentary side view showing the parts shown at the extreme right-han end of Fig. 1.

The yarn cleaner shown in the figures has a regular frame 110, the ends of which are provided at their middle with recesses 120, 121 which permit a yarn A. to be drawn longitudinally across the middle of the frame below the upper edge thereof. To the end 113 of the frame, which is termed the front end because it is the end from which the traveling yarn enters the cleaner, is attached a tension device 119 which retains the yarn under tension as it is drawn across the frame of the cleaner.' The tension device illustrated forms the subject matter of my Patent No. 1,456,263, issued May 22,

1923, and is, therefore, not described in detail or claimed herein.

The top of the frame 110 may be closed by a two-piece cover 126 which provides a slot extending from recess 120 to recess 121. A skirt 13:2. extends downwardly1 from the Divided and this application filed .Tune

frame to confine the impurities removed Vfrom the yarn in the cleaner.

The sides 115, 116 are of considerable width and have in their upper surfaces guideways 11T. 117 extending between the guide holes 141 in the ends 113, 114 of the frame. Two slide bars 140, 140 are mounted to rest in the slots 11T, 117 and to entend through the guide holes 141 of the frame. The slide bars 140. 140 are mounted to rest in the slots 117, 117 and to extend through the guide holes 141 of the frame. The slide bars 140, 140 extend through the rear end 114 of the frame and have mounted on the outer ends thereof short vertical bars 142, 142 respectively, each of which contains a vertical slot 143 extending in from its lower end. Slots 143 embrace eccentrics 144, 144 mounted on opposite ends of a transverse shaft 145 which is positioned below the bottoms of recesses 120, 121 and is journalled in a bracket 146 secured to the rear end 114 of the frame. ln an operative condition the shaft 145 is rotated at high speed, being driven, for example, by a belt passing over a pulley wheel 147. The rotation of the shaft causes the eccentrics`144, 144 to give the slide bars 140, 140 a rapid reciprocatory movement. This movement is very short owing to the fact that the throw of the eccentr-ics 144, 144 is only a few hundredths of an inch, being exaggerated in the drawings for the sake of clearness.

The cleaner is provided with reciprocatory elements which serve to clean the yarn and to direct the matter removed from the yarn out of the cleaner. Two types of such elements, the cleaning elements 150, 150 and the cleaning and deflecting elements 170, 170', are shown in the drawings.

Each reciprocatorv cleaning element 150 comprises a cleaning blade 153, inclined towards the front end 113 ofthe frame, and a support 152, inclined toward the rear end of the frame, and pivotally secured at its outer end to the slide bar 140 by means of screw 156. Each support 152 contains a slot 157 which embraces aI pin 158 on the side 115 of the frame. As a result, reciprocatory movement of the slide bar 140 moves the inner edges of the blades 153 in a curve tangentia to the yarn. The pins 158 are positioned so that the inner edges of the blades 153 are close to the yarn at the middie point el each i'eci} noeation ot the slide Htl bai' 140. The supports 152- ofthe Ielements 150 are mounted in the saine Way as the supports 152.

In the end oteach-ol'fitlie cleaning blades 153, 153 is a semi-circular notch 159, 159

respectively extending" substantiallyparallel i l edge `175 which is Fperpendicular to thesupport 172` and isinclined to the line` of the travel oi the yarn by reason oftheinclinay tion otitlie blade. `The cleaning and deflectging elements 17 0" are similar to the elements 170y except that each ofwtliein ibas in its. inner edge 175 a semi-elliptical notch 180 cleaner without being deflected downwardly l extending substantially parallel to the slide are pivotally .secured at their` outenends to dareipinotallysecui'ed to theside 115. of the Theisupports 172 of alternate elements 17 0 the 'side 115 of tlietraine 110 `by means of `,screws 176 located inside `the slide barE 140.
